For MythTV I want my NVIDIA GeForce 3 TI 200 to output through its SVIDEO OUT to my Sony 30" HDTV. I've been trying to set this up with twinview because I know I can make the monitor work, and I can make edits on the monitor then try them with the TV. Welp, I can't get the TV to pick up any signal from the svideo out on the GeForce 3. I haven't tried a configuration with the TV as the only monitor, but I suppose I could if that's the only way it might work.

i'm not sure my geforce3 did twinview. i put in a newer nicer geforce4 from a different computer of mine and everything worked great. it was enabled automatically at boot time, and when X started, it seemed to do twinview just fine. not sure whether that had more to do with the X config or the card since it was outputting to both tv and monitor from the moment it booted. anyway, i don't care so much about twinview as getting the svideo out on my geforce3 working with X since ii ultimately just want to run mythtv or freevo with it.
